Royal Observatory Greenwich

Royal Observatory Greenwich

The Royal Observatory in Greenwich is the home of British astronomy and navigation. Built in the 17th century, it has witnessed how great scientists of the time mapped the stars with exceptional accuracy to aid navigation at sea.

With this ticket, you'll get to visit the place that gave its name to Greenwich Mean Time (GMT) and see the prime meridian of the world, the exact point where East meets West  - 0° 0’ 0”! You'll even get to stand on it!

During the tour, you'll have an audio guide that will tell you all about the astronomical advances that were made at this centre throughout history. 

Opening Hours

The Greenwich Observatory is open every day from 10 am to 5 pm. Last admission is at 4:30 pm.
